iPod/mp3 genres -- help!

Prompted by Momus talking about 'Experimental' here, these are my current thoughts:

I am finding adding genre tags to my MP3s an infuriating and thought-provoking exercise. The automated CDDB service makes loads of things 'Alternative/Punk', which I hate. I have added the genre 'Avant Garde' to cover things like Eno and Disco Inferno, made most 'Alternative/Punk' things just 'Rock', and reserved 'Alternative' for noisy, awkward sounding guitar based things. The other thing I am now trying to do is treat all tracks individually, rather than assume that everything by an artist necessarily belongs in the same genre. Even within an album. So tuneful Fall tracks get 'Rock' and others get 'Alternative' or maybe 'Avant Garde'. But I fear this particular aspect of the job will drive me insane.

One thing I haven't really dealt with is retro-sounding pop made by indie artists. Soundwise, they have most in common with old songs I have categorised as 'Pop', but am reluctant to use that for indie things that are removed from the commercial arena in which their templates existed. I have ended up using 'Indie Pop', but that seems kind of crass, and anyway I don't know if that's appropriate for St Etienne tracks that aren't really 'Dance' or 'Electronic' either.

I know I'll never reach a consistent set of rules, but the process of straining towards it is interesting. Well interesting me, anyway.

no.

How about Captain Beefheart?

Great Plains?

Half Japanese? (greatest hits, which seems to run the proverbial gamut)

Proverbial Gamut?

Urinals?

Wipers?

Pre Imperial ffrr Unrest?

TV on the Radio???

Even something like Replacements confuses. I was thinking of making a genre of OBCBYL. I don't know...

Why am I wasting my time doing this?

bhangra
electronica
grime
hiphop and triphop
jungle and dnb
miscellaneous
mixes
reggae, dancehall, and dub
soundtracks

It works pretty well, actually.
